The Defenders

Originally, the Defenders were Doctor Strange, the Sub-Mariner, and the Incredible Hulk. Soon, however, this star-crossed super-group began what would have been a never-ending series of personnel replacements. Nighthawk, the Cat, Valkyrie, Moondragon, the Gargoyle, and countless others at one point called themselves Defenders.

The list of their foes was equally long. Most distinguished among them was Greg Salinger, a murderous psychopath who called himself “FoolKiller.” Although the Defenders were eventually able to bring him to justice, his ideas inspired yet another person to take up the role of the FoolKiller, and the carnage continued. (The story of the new FoolKiller is told in the powerful FoolKiller mini-series.)
